IMPROVEMENT m THE CONSTRUCTION OF LAMF-BURNERS.

Specification forming part of Letters Patent No. 131,917, dated October1, 1872.

To all whom it may concern: v

Be it known that I, WILLIAM N. WEEDEN, of Waterbury,in the county of NewHaven and State of Connecticut, have invented a new and usefulImprovement in Lamp-Burners; and I do hereby declare that'the follow- Iing is a full, clear, and exact description of the same, reference beinghad to the accompanying drawing forming part of this specification, andin which- Figure 1 represents a top View of a lampburner constructed inaccordance with my invention; Fig. 2, a vertical section of the same atthe line as m; Fig. 3, a top view of a blank as domed up to prepare itfor being formed into a chimney-holder, chimney-rest, and cone-support;Fig. 4, a section of the same at the line 3 y,- and Fig. 5, a top viewof said portion as finished and ready to receive the cone, which latteris shown detached in Fig. 6.

Similar letters of reference indicate corresponding parts.

My invention consists in a novel construction of that portion of alamp-burner which comprises the chimney-holder, the chimneyrest, and thecone-support, which are all struck or formed out of the same piece ofsheet meta1, without waste, thereby economizing the construction of theburner both as regards labor and material.

To make the combined chimney-holder, chimney-rest, and cone-support, Ifirst stamp out and dome up a sheet-metal blank, A, substantially asillustrated in Figs. 3 and 4, leaving radial upper swells or braces ona. and a rim, b.

CASE B.

The portions between the radial swells a a are then stamped or cut andbent, as illustrated in Figs. 1,2, and 5, to form upper radialspringarms 0 c, which constitute the chimney-holder, the same bearing orpressing against the interior of the chimney, While the rim b forms therest or seat for the chimney, and the radial swells or braces a aconstitute the cone-support, thus utilizing the whole metal of the blankand economizing labor in construction, as well as saving metal, over oras compared with the making of the chimney-holder, the chimney-rest, andthe cone-support of difl'erent pieces, besides giving increasedstability tothe structure. The cone B is formed of a separate piece ofmetal struck to match the' springs c c, and having horns d d cut fromwithin acircu nscribing circle, as shown in Fig. 6. Such cone is shapedto lit snugly on the inner portions of the springs c c, and the horns dd bent to enter apertures e c in the springs c 0, below which they areturned to clamp the cone to the springs. in this way the cone issupported by and also stiffens or strengthens the springs-of thechimney-holder.

I What is here claimed, and desired to be secured by Letters Patent, is

In a lamp-burner, the construction of the chimney-holder, thechimney-seat, and the cone-support of one and the same piece of metal,substantially as herein described.
